CiA 301 and CiA 402

Stepper drives with CANopen

The STAC6-C stepper drive by Applied Motion Products (US) is a two-phase, bipolar step motor drive for high-torque applications. It complies with CiA 301 and CiA 402.

THE PRODUCT OPERATES ON SINGLE-PHASE 120 VAC and outputs up to 6,0 A/phase (peak-of-sine) to the step motor. It features over-voltage, over-temperature, and over-current protection and is complemented by a matched set of low-loss NEMA 23 and NEMA 34 frame step motors.

The product is designed to operate on a CANopen communication network and conforms to the CiA 301 and CiA 402 specifications. It supports profile position, profile velocity, and homing modes, as well as the ability to run stored Q programs via Applied Motion-specific CANopen objects. For connecting to external devices such as limit switches, proximity or photoelectric sensors, PLC I/O, lamps, and other devices, the stepper drive comes with seven digital inputs, three digital outputs, and two single-ended analog inputs (analog inputs can be wired together as one differential analog input).

The stepper drive comes with a CANopen port for connecting to the CANopen data network. Each drive comes with an encoder feedback connector for applications that demand a higher level of position. The user can use the company’s double-shaft step motors with incremental encoders and activate either Stall Detection or Stall Prevention in the drive. Stall Detection notifies the system as soon as the required torque is too great for the motor, which results in a loss of synchronization between the rotor and stator, also known as stalling. Stall Prevention automatically adjusts motor speed to maintain synchronization of the rotor to the stator under all conditions. This feature allows step motors to operate in a much broader range of applications than previously possible, such as torque-control. The Stall Prevention feature also performs static position maintenance, which maintains the position of the motor shaft when at rest. Additionally, the inclusion of the optional encoder allows the motor to be precisely homed to the index (marker) pulse.
